TO ALL WHGM Ill.'l MAY CONCERN: i y 4 l Be it knownj that I, H, G. TAYLOR, of lcn't Hope, in the Province of. Canizde. West, have invented a new and rnproved Combination` of Square and Bevel; and that -the following description, teken in'connectio'n withf the accompanying drawings, hereinafter referrdd to, lformen); full and exact'specification of the same, wherein I have set. forth the nature and principlesv of my scid improveiients, by which my invention may be'. distinguished from all others of e similar class, together with s'ch parts as I'clnini,a.nd desire. to have secured to me by Letters Patent. l l Y u .Y

This invention consists in a new and improved combingntion cfa square nd'bevel,vvhereby.the blade may be set to any required angle or'bevel, and, at the same time, a square be always preserved.

'Thelinvention diers very Vmaterially from an ordinary bevehand alsolfro'm all othercombined-bevels-an'd squares which have come under my observation, as the square lis,a.lvniys preserved under every adjustment of the device as a bevel.' ,d l

In 4the vacconiptmyng sheet of drawingst Figures 1 and 2 are side views `of the invention.

The stock oiy the device iecomposed of two 'pai-ts, A A', which, in 'this instance, are one,-A, of crescent form, and the other, A', of trilateral form, 'with a. curved or concave bsse,f'constructed of metal,'and conneoted together, st ther centre, by a screw and nut, B. These two partshave ench'pinma, projecting from their at right' angles,lone at cach end of their bases, and the part A has a' recess in its under eide, in 'which the blade C of the device is fitted, the blade being at`i'ig'bt angles with tbe'line of `thcpins a of sixid part, and the inner surface of the'blade'flush with the inner surface ofthe part A, sol that the two-parts A A may have their' inner surfaces in contact. n i d v i The part A is'giaduated, as 'shown at 6, into' the degrees of al part of e circle, und the bevel is obtained by lowering the nut of screw B, und adjusting the blade' 1C to any angle required; and, in using the bevel, the pins a a of the part A are placed in contact with the surface, with which' Ythe blade C, forms the angle,- ad, when e square is required, the pins a of'the part' A are placed against said surface, the device being invcrtedtce'ec that end.

Thus, it will he seen theta square and bevel Varc obtained by n. very simple arrangement, the part A ofthe stock and the blade comprising the square, the relntive positions of which cre never changed, 4sindV the part A." of the stock and the blade forming the bevel, the twopartsA being prevented from casually moving by means of the screw and nut vB. v

Having thus described my invention, I claim asnew, and desire tosecure by Letters Patent- A 'combined sqerc and bevel, composed 0f a stock, formed of two pertsfA A', connected by a screwl and nut, B, andra blade, C, fitted between said parts, and connected with part A, all arranged substantially as shown end dcscribed. f
